The Natural Resources Mapping of Champhai District using Remote Sensing and GIS was undertaken by the Mizoram State Remote Sensing Centre (MSRSC), Science, Technology & Environment Wing, Planning Department, Government of Mizoram, under the Natural Resources Mapping of Mizoram programme sponsored by the North Eastern Council (NEC), Shillong. The study forms part of a three-year state-wide initiative to develop an integrated geospatial database of Mizoram's natural resources using Remote Sensing (RS), Geographic Information System (GIS), GPS-assisted field surveys, and conventional resource mapping techniques. The primary objective was to generate standardized thematic maps and digital spatial datasets for sustainable management of land, water, forests, and other natural resources while supporting scientific planning and policy formulation.The study covers the entire Champhai District, extending over 3,185.83 sq. km, accounting for approximately 15.11% of the geographical area of Mizoram. The project utilized IRS-1D LISS-III and Panchromatic satellite imagery (2003–2004), Survey of India topographic maps, meteorological records, geological information, and extensive field verification to prepare thematic layers on land use/land cover, geology, geomorphology, soils, drainage, watershed boundaries, groundwater potential, slope, aspect, elevation, settlements, and transportation networks. These datasets were integrated within a GIS environment to facilitate resource assessment and formulate district-specific action plans.The analysis reveals that Champhai District is characterized by rugged hill ranges interspersed with broad intermontane valleys, particularly the fertile Champhai Valley, making it one of Mizoram's most important agricultural regions. Terrain analysis indicates that the district is predominantly mountainous, with land capability and agricultural suitability closely controlled by slope and elevation. Geological mapping identifies sedimentary formations of the Surma Group as the dominant lithology, while geomorphological analysis highlights structural hills, valleys, flood plains, and denudational features that govern drainage and land-use patterns.Land use and land cover assessment indicates that forest and bamboo forest remain the dominant land cover, reflecting the district's rich ecological resources. However, current shifting cultivation (jhum) occupies approximately 164.48 sq. km (5.16%), while young abandoned jhum lands cover about 561.44 sq. km (17.62%), emphasizing the continued influence of traditional shifting cultivation on the landscape. The report also documents the expansion of horticultural plantations, wet rice cultivation in valley floors, and permanent agriculture, indicating a gradual transition towards more sustainable land-use systems in suitable areas.The study further evaluates soil characteristics, groundwater prospects, and watershed conditions to identify areas suitable for agricultural intensification and water resource development. Soil investigations reveal predominantly acidic hill soils with moderate fertility and high susceptibility to erosion on steep slopes, underscoring the need for integrated soil and water conservation measures. Watershed-based analysis provides a scientific framework for rainwater harvesting, groundwater recharge, and sustainable watershed management.A major outcome of the project is the development of a comprehensive natural resources information for Champhai District, integrating multiple thematic datasets into a GIS platform for resource planning and spatial decision-making. Based on the integrated assessment, the report recommends watershed development, afforestation, agroforestry, horticultural expansion, sustainable agricultural practices, groundwater development, and land capability-based planning to optimize resource utilization while conserving the district's fragile mountain ecosystem.Overall, the project demonstrates the effectiveness of integrating Remote Sensing, GIS, GPS, and field investigations for comprehensive natural resource assessment in mountainous regions. The thematic maps, digital databases, and development plans generated under the study provide an invaluable reference for planners, researchers, government agencies, and development organizations, supporting evidence-based planning and the sustainable management of Champhai District's natural resources.Summarized MetadataMapping Scale: 1:50,000Satellite data & Year: IRS 1D PAN & LISS III (2003 & 2004) – Digital & Photo printThematic sub-category: Land Use/Land Cover, Geology, Water resource, Climate, Action Plan Collaborating/Funding Agency: North Eastern Council (NEC), ShillongReport Publication Month/Year: July, 2006

The Natural Resources Mapping of Aizawl District using Remote Sensing and GIS was undertaken by the Mizoram State Remote Sensing Centre (MSRSC), Science, Technology & Environment Wing, Planning Department, Government of Mizoram, under the Natural Resources Mapping of Mizoram programme sponsored by the North Eastern Council (NEC), Shillong. As part of a state-wide initiative implemented in a phased manner, the project aimed to establish a comprehensive geospatial database of Aizawl District using Remote Sensing (RS), Geographic Information System (GIS), GPS surveys, and field investigations. The study was designed to provide scientifically validated information for sustainable management of land, water, forests, and other natural resources while supporting evidence-based planning across multiple development sectors.The study covers the entire Aizawl District, encompassing a geographical area of approximately 3,576.31 sq. km, representing one of the largest administrative districts in Mizoram. Multi-source datasets, including IRS-1D LISS-III and Panchromatic satellite imagery, Survey of India topographic maps, geological information, meteorological records, and detailed field observations, were integrated within a GIS environment to prepare thematic maps on land use/land cover, geology, geomorphology, drainage, watersheds, groundwater potential, slope, aspect, soils, settlements, and transport networks. The integration of these datasets enabled comprehensive assessment of the district's natural resource potential and constraints.The investigation reveals that Aizawl District is characterized by rugged north-south trending hill ranges, steep slopes, and deeply dissected river valleys, making terrain one of the dominant factors influencing land use and development. Forests continue to be the principal land cover, with bamboo forests occupying the largest proportion of the district, followed by medium and dense forests, highlighting the district's rich biodiversity and ecological significance. However, the study also identifies current and abandoned shifting cultivation (jhum) as important landscape components, reflecting the continued dependence of rural communities on traditional agricultural practices. Expansion of horticultural plantations and permanent agricultural land in suitable valleys and gentle slopes indicates a gradual transition towards more sustainable land-use systems.Groundwater assessment shows that the district possesses localized zones of moderate groundwater potential, primarily associated with fractured sandstone formations and valley fills, while much of the hilly terrain exhibits limited groundwater availability due to steep slopes and rapid surface runoff. Soil investigations reveal predominantly acidic hill soils with moderate organic carbon content but varying fertility and erosion susceptibility depending on terrain conditions. The study also delineates watershed boundaries and evaluates drainage characteristics, providing a scientific basis for watershed development, rainwater harvesting, and integrated water resource management.A major outcome of the project is the development of a district-level natural resources information, integrating multiple thematic layers into a GIS platform for spatial analysis and planning. Based on the resource assessment, the report recommends watershed management, soil and water conservation, afforestation, agroforestry, horticultural expansion, groundwater development, and land capability-based planning to promote sustainable utilization of natural resources while minimizing environmental degradation.Overall, the project demonstrates the value of integrating Remote Sensing, GIS, GPS, and field-based investigations for comprehensive natural resource assessment in mountainous regions. The thematic maps, digital databases, and resource development plans generated under the study provide an important reference for government agencies, planners, researchers, and development organizations engaged in sustainable environmental management and regional planning. By establishing a standardized geospatial database, the project continues to serve as a valuable foundation for natural resource conservation, infrastructure planning, watershed development, and future geospatial studies in Aizawl District.Summarized MetadataMapping Scale: 1:50,000Satellite data & Year: IRS 1D PAN & LISS III (2003 & 2004) – Digital & Photo printThematic sub-category: Land Use/Land Cover, Geology, Water resource, Climate, Action Plan Collaborating/Funding Agency: North Eastern Council (NEC), ShillongReport Publication Month/Year: June, 2006

The Natural Resources Mapping of Kolasib District using Remote Sensing and GIS was undertaken by the Mizoram State Remote Sensing Centre (MSRSC), Science, Technology & Environment Wing, Planning Department, Government of Mizoram, under the Natural Resources Mapping of Mizoram project sponsored by the North Eastern Council (NEC), Shillong. The study forms part of a state-wide initiative launched in 2004 to develop a comprehensive geospatial database of Mizoram's natural resources through the integration of satellite remote sensing, Geographic Information System (GIS), GPS surveys, and field investigations. The primary objective was to generate accurate thematic maps and digital spatial datasets that would support sustainable land and water resource management, environmental planning, and informed decision-making at district and state levels. The project covers the entire Kolasib District, the northernmost district of Mizoram, extending over 1,382.51 sq. km, representing approximately 6.56% of the state's geographical area. IRS-1D LISS-III and Panchromatic satellite imagery acquired during 2003–2004 formed the primary data source, supplemented by Survey of India topographic sheets, geological and meteorological records, soil investigations, and extensive ground verification. A standardized workflow comprising pre-field image interpretation, GPS-assisted field validation, laboratory analysis, and GIS integration was adopted to generate thematic layers on transport network and settlements, drainage, watershed boundaries, geology, geomorphology, slope, aspect, groundwater potential, soils, and land use/land cover, culminating in district-level land and water resource development plans. The study reveals that Kolasib is predominantly a hilly district, with low structural hills occupying about 91.94% of the total area, while valley fills and flood plains together account for less than 5%, indicating limited terrain suitable for intensive agriculture. Geologically, the district is dominated by siltstone and shale formations (77.99%), followed by sandstone (19.32%), with recent alluvial deposits occurring mainly along major river systems such as the Tlawng, Tuirial, and Serlui. Land use analysis demonstrates that forest remains the dominant land cover, with bamboo forests alone covering 657.40 sq. km (47.55%), while medium and dense forests together account for over 23% of the district. Current and abandoned shifting cultivation (jhum) occupy approximately 200.44 sq. km (14.50%), highlighting the continued influence of traditional agricultural practices on the landscape. The assessment also documents the growing importance of horticulture, including arecanut, citrus, coffee, banana, pineapple, and black pepper plantations, which represent a gradual transition towards more sustainable land-use systems. Groundwater potential mapping indicates that 33.07% of the district possesses moderate groundwater potential, whereas 37.24% falls within the poor potential category because of steep topography and rapid surface runoff. Soil investigations identified predominantly acidic red and yellow loamy soils belonging to the Entisols, Inceptisols, and Ultisols orders, characterized by high organic carbon and nitrogen content but comparatively low phosphorus and potassium availability. The report further classified land irrigability and hydrosoil characteristics, providing a scientific basis for selecting suitable agricultural practices and water management strategies. A major outcome of the project is the preparation of integrated land and water resource development plans based on GIS analysis of multiple thematic layers. The study identifies opportunities for watershed development, rainwater harvesting, groundwater exploration, soil conservation, afforestation, agroforestry, horticultural expansion, and scientific land capability planning. By combining satellite-derived information with field observations and spatial modelling, the project establishes a comprehensive natural resource information system for Kolasib District. The generated maps, datasets, and development plans provide a valuable reference for government agencies, researchers, planners, and development organizations, enabling evidence-based planning and promoting the sustainable management of natural resources in one of Mizoram's most strategically important districts. Summarized MetadataMapping Scale: 1:50,000Satellite data & Year: IRS 1D PAN & LISS III (2003 & 2004) – Digital & Photo printThematic sub-category: Land Use/Land Cover, Geology, Water resource, Climate, Action Plan Collaborating/Funding Agency: North Eastern Council (NEC), ShillongReport Publication Month/Year: September, 2005

The Natural Resources Mapping of Mamit District using Remote Sensing and GIS was undertaken by the Mizoram State Remote Sensing Centre (MSRSC), Science, Technology & Environment Wing, Planning Department, Government of Mizoram, as part of the Natural Resources Mapping of Mizoram project funded by the North Eastern Council (NEC), Shillong. The study forms one phase of a state-wide geospatial resource inventory programme initiated in 2004 to develop an integrated spatial database for sustainable natural resource management using Remote Sensing (RS), Geographic Information System (GIS), GPS surveys, and field investigations. The principal objective was to generate standardized thematic maps and digital databases to support scientific planning, conservation, and sustainable utilization of land and water resources while facilitating informed decision-making by government departments and development agencies.The project covers the entire Mamit District, occupying approximately 3,025.75 sq. km, making it one of the largest districts in Mizoram. IRS-1D LISS-III and Panchromatic satellite imagery, Survey of India topographic maps, geological and meteorological information, soil surveys, and extensive field verification were integrated within a GIS environment to prepare detailed thematic layers on transport and settlements, drainage, watershed boundaries, groundwater potential, geology, geomorphology, slope, aspect, elevation, land use/land cover, and soils. These datasets were subsequently synthesized to formulate district-specific action plans for land and water resource development.The study reveals that Mamit District is characterized by rugged hill terrain, with north-south trending ridges dissected by major river systems including the Tlawng, Teirei, Tut, Langkaih, Mar and Khawthlangtuipui Rivers. Terrain analysis indicates that steep and moderately steep slopes dominate much of the district, limiting the availability of land suitable for intensive agriculture while increasing susceptibility to soil erosion. Aspect analysis further highlights that eastern- and western-facing slopes together account for nearly one-third of the district, reflecting the characteristic structural orientation of the hill ranges and providing valuable information for agricultural planning, horticultural development, and watershed management.Land use and land cover assessment demonstrates that forests and bamboo forests constitute the dominant land cover, reflecting the district's rich natural vegetation. However, substantial areas remain under current and abandoned shifting cultivation (jhum), indicating the continued dependence of local communities on traditional agricultural practices. The study also records expanding horticultural plantations and agricultural activities in suitable valley lands and gentle slopes, illustrating an increasing transition towards more permanent and sustainable land-use systems. Groundwater potential mapping identifies distinct zones of varying groundwater prospects, providing a scientific basis for locating future groundwater development, while detailed soil investigations reveal predominantly acidic hill soils with moderate to high organic matter but varying fertility and erosion susceptibility depending on topographic conditions.A major outcome of the project is the development of an integrated natural resources information that combines multiple thematic datasets within a GIS framework to support evidence-based planning. Based on the spatial analysis, the report proposes comprehensive action plans emphasizing watershed development, rainwater harvesting, soil and water conservation, afforestation, agroforestry, horticultural expansion, sustainable agriculture, and scientific land capability-based planning. These recommendations are designed to optimize resource utilization while minimizing environmental degradation.Overall, the project demonstrates the effectiveness of integrating Remote Sensing, GIS, GPS, and field-based investigations for comprehensive natural resource assessment in mountainous regions. The geospatial database, thematic maps, and development plans generated under the study provide an invaluable reference for planners, researchers, resource managers, and policymakers, supporting sustainable development and long-term management of Mamit District's land and water resources. Summarized MetadataMapping Scale: 1:50,000Satellite data & Year: IRS 1D PAN & LISS III (2003 & 2004) – Digital & Photo printThematic sub-category: Land Use/Land Cover, Geology, Water resource, Climate, Action Plan Collaborating/Funding Agency: North Eastern Council (NEC), ShillongReport Publication Month/Year: September, 2005
